  • Page 23: Air Preparation Unit - Air Pipes

    M1 – M3 AG 4. AIR PREPARATION UNIT – AIR PIPES 4.1. Air preparation unit Air gaging is a measurement of pressure variation. The variation of pressure must be due to the variation of distance between the gage and the part being measured. Therefore, it is mandatory to have a high stability air input, in order not to have variation of pressure due to air input variation.
  • Page 24 “eco” mode, depending on the instruction given by the module. The principle: Following a period without action (no pressure variation, no touch screen, etc.), the M1/M3 will send a command to the regulator which will switch to a much lower pressure (1 bar) to supply the air gage.

  • Page 25: Air Pipes

    4.2. Air pipes The M1/M3 are fitted with air connectors adapted to connected pipes with 6mm external diameter and 4mm internal diameter. In the case of the M3, it is however recommended to use an 8mm ext. tube from the output of the air preparation unit to a Y connection/reduction to 6mm to the display.

    M1 – M3 AG 14.5.3. Principle of compensation in measurement mode – use cases The temperature compensation ables to compensate the temperature’ expansion of a part and to estimate what its size will be after cooling. In the following example, we will consider the measurement of a 50mm mild steel ring.

    M1 – M3 AG Specific setting of the page 1 for our use cases We specify the formula to be entered for each characteristic. In our example, we compare the normal characteristic and the compensated characteristic of the channel A.
  • Page 107 M1 – M3 AG Both characteristics display 50.000 mm at 20°C, this is the expected result. We heat the part at 50°C. We expect an expansion of 18µm (50 * 12E-6 * (50-20) = 18 µm) The « compensated characteristic », stayed at 50.000mm thanks to the compensation.

    If the cycle time is important, we have solutions to accelerate. - The length of tubes between the air gage and the M1/M3 AG module is very important and has an impact on the stabilization time. The longer the pipe, the longer it will take for the measurement to stabilize.
